DETAILED DESCRIPTION

Reference will now be made in detail to exemplary aspects of the present invention which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or similar parts.

FIGS. 1-9 illustrate a bag dispenser 10 having features that are examples of inventive aspects in accordance with the present disclosure. According to one example embodiment, the bag dispenser 10 is generally configured to be used by consumers in stores such as grocery stores for bagging items such as produce, confectionary, etc. The bag dispenser 10 illustrated in FIGS. 1-9 is configured to be a type of bag dispenser, wherein the dispenser is configured or easily configurable to be able to be used with bags made by various different manufacturers as will be discussed below in further detail.

Referring to FIGS. 1-9, the bag dispenser 10 includes a frame 12 that is mounted on a dispenser support 14. The frame 12 of the bag dispenser 10 may be removably mounted to the dispenser support 14 via fasteners 16. The dispenser support 14 may include a base for attaching the dispenser to a ground surface such as in a store. According to one example embodiment, the dispenser support 14 might include a base post attached to the base, a head post 18 to which the frame 12 is mounted, and an intermediate post 20 that is positioned between the base post and the head post 18 that allows adjustability of the height of the frame 12 with respect to the base. The height-adjustability may be provided by holes provided on the intermediate post 20 and spring loaded pins 22 provided on both the base post and the head post 18. The spring loaded pins 22 snap in to the holes on the intermediate post 20 for locking the frame 12 of the bag dispenser 10 at discrete locking positions to provide for different heights.

The bag dispenser 10 includes a roller 24 for mounting a bag roll 26. According to the depicted embodiment, the roller 24 is attached to the frame 12 with a support arm 28. The roller 24 is stationary with respect to the frame 12 and generally includes a circular configuration to allow the core 30 of the bag roll 26 to rotate during dispensing. The roller 24 and the support arm 28 are positioned and spaced within the frame 12 such that even a full bag roll 26 can rotate on the roller 24 without any portion of the frame 12 contacting the bottom surface 32 of the bag roll 26.

According to the embodiment depicted in FIGS. 1-9, the support arm 28 may be a pivot arm that allows the roller 24 to be pivoted upwardly for replacement of the bag roll 26. The frame 12 includes a containment arrangement defining rails/guards 34 for preventing the bag roll 26 from sliding off the roller 24 once the bag roll 26 is slidably placed on the roller 24. The pivot arm 28 allows the roller 24 to be pivoted upwardly in order for the bag roll 26 to clear the rails 34 during loading of the bag roll 26.

Even though in the embodiment depicted in FIGS. 1-9, the pivot arm 28 is configured to allow the roller 24 to pivot along a plane parallel to the dispending direction D (clockwise/counterclockwise when looking in the direction of the longitudinal axis of the core), it should be noted that in other embodiments, the roller 24 might be pivotally attached to the arm 28 such that the roller 24 pivots with respect to the arm 28 and along a plane that is perpendicular to the dispensing direction D (clockwise/counterclockwise when looking in the dispensing direction, at the front of the bag roll). As will be discussed in further detail below, other arrangements may be used to prevent the bag roll 26 from sliding off the roller 24 once the bag roll 26 is placed on the roller 24.

The bag dispenser 10 includes a first braking arrangement 36 for providing frictional force on the leading bag 38 when a consumer pulls the leading bag 38 to facilitate tearing of the bag 38 at a tear line. The bag dispenser 10 also includes a second braking arrangement 40 to reduce the rotational speed of the bag roll 26 to prevent freewheeling of the bag roll 26 after a consumer pulls and tears the leading bag 38.

Both the first and the second braking arrangements 36, 40 are the types of arrangements that accommodate bag rolls 26 of different manufacturers, for example, bag rolls that might include a different bag thickness/material, a different core diameter, a different weight, etc.

The first braking arrangement 36 includes a removable braking plate 42 that includes two openings 44 for slidably mounting the plate 42 through two posts 46 located adjacent the front of the frame 12. The braking plate 42 is shown in isolation in FIG. 11. The braking plate 42 is made removable such that regardless of the type or weight of bag used, the plate 42 can be easily removed and interchanged with a different one to provide the necessary frictional force on the leading bag 38 to facilitate tearing of the bag 38.

In the depicted embodiment, the braking plate 42 cooperates with a braking surface 48 to provide at least one point of contact 50 therebetween for the application of friction. The braking plate 42, even though heavy enough to apply a frictional force to the bag, is also able to move up and down and float via its mounting arrangement to allow for variations in the bag texture and/or thickness.

As noted above, the second braking arrangement 40 is of the type that may be used with a variety of different bag rolls 26 having a variety of different core diameters. According to the embodiment depicted in FIGS. 1-9, the roller 24 includes a surface 52 that provides friction to the internal surface 54 of the core 30 of the bag roll 26. The friction surface 52 of the roller 24 might be provided in different ways, for example, using surface texturing, using a material of relative high static and kinetic coefficient of friction, using an adhesive material to provide a tacky surface, etc. With the application of enough friction, once the leading bag 38 is torn off, the rest of the bag roll 26 does not freewheel within the frame 12. Furthermore, the friction surface 52 provided by the roller 24 allows the roller 24 to be a smaller size than the core 30, allowing the second braking arrangement 40 to be a braking arrangement that can be used with bag rolls 26 having different core diameters. With the cooperation of the first braking arrangement 36 provided by the removable plate 42, the second braking arrangement 40 allows for any variation in the weight, type, material, thickness, tear line configuration, and core diameter of a given bag roll 26.

Even though a roller 24 having a friction surface 52 is used in the embodiment depicted in FIGS. 1-9, in other embodiments, as will be discussed in further detail below, other types of arrangements may be used to prevent freewheeling of the bag roll 26 after dispensing of the leading bag 38.

Still referring to FIGS. 1-9, the bag dispenser 10 includes an interchangeable tongue structure 56 that is mounted to the frame 12 with fasteners 59 (as shown in FIG. 5). The tongue structure 56 is mounted to the frame 12 in front of the braking plate 42 and is configured to provide support to the leading bag 38 as the leading bag 38 is being pulled by a consumer. The tongue structure 56 includes a pincher/perforator 58 at the front end for perforating the bag roll 26 and separating the leading bag 38 from the adjacent bag at the tear line. Although different types of pinch points can be designed for catching the adjacent bag after the leading bag 38 has been torn off, in the depicted embodiment, the pinch point 60 is created by the interaction of a flat surface 62 provided by the pincher/perforator 58 and a curved surface 64 provided by a front rail 66 of the tongue structure 56.

The removability and interchangeability of the tongue structure 56 allows for mounting different types and numbers of pinchers/perforators 58 for different manufacturers of bags. For example, if a bag roll includes two perforation points, two perforators 58 might be needed, one at each side at the front of the tongue structure.

Referring now to FIGS. 10 and 15, the bag dispenser 10 includes an accessory mount 68 for mounting various different types of structures 70 such as twist-tie dispensers or other accessory holders adjacent the bag dispenser 10. The accessory mount 68 can be attached to the frame 12 with mechanical fasteners or other fastening means such as welding, etc. According to the depicted embodiment, the accessory mount defines a U-shaped bracket 72 that can be used, for example, to mount an accessory holder 70 using a nut/bolt/washer fastening arrangement. The U-shaped bracket 72 of the accessory mount 68 also allows other types of accessory holders 70 such as containers or cups to be hung from the accessory mount 68, wherein the accessory holders could hold twist-ties, coupons, etc. An example accessory holder 70 is shown diagrammatically with dotted lines in FIG. 10.

Referring now to FIGS. 10 and 12-14, the dispenser support 14 of the bag dispenser 10 allows the bag dispenser 10 to pivot along a plane generally parallel to a ground surface on which the dispenser support 14 is mounted, allowing a consumer to be able to pull the leading bag 38 of the roll 26 at angles other than parallel to the dispensing direction (dispensing direction indicated by arrow D).

In addition to allowing for height adjustment, the intermediate post 20 of the dispenser support 14 may include a pivot groove 74 that interacts with a spring loaded pin 22 of the head post 18 for allowing the frame 12 to be pivoted left to right. According to one embodiment, the pivot groove 74 may be a self-centering groove that includes a generally V-shape or a curved shape as seen in FIGS. 12-14. The shape of the groove 74 guides the pin 22 and uses gravity in allowing the weight of the bag dispenser frame 12 in pivoting the dispenser 10 to the original starting position after a consumer has torn off the leading bag 38. When the bag 38 is torn, the spring loaded pin 22 rides in the groove 74 toward the bottom 76 of the groove 74 to self center the bag dispenser frame 12. In this manner, the stores can maintain a neat appearance with all of the bag dispensers 10 facing in the original dispensing direction. FIGS. 12-13 illustrate the bag dispenser 10 in a non-pivoted or returned-to-original position. FIG. 14 illustrates the pivot structure when the bag dispenser 10 has been pivoted to the right by a consumer.

It should be noted that the groove/pin arrangement is one example method of providing a pivoting and self-centering feature of the bag dispenser 10 and other arrangements may be used to provide for this type of a feature.

Still referring to FIG. 10, in another embodiment of the bag dispenser 100, the tongue 156 may include two bag pivot contact structures 102 depicted as posts. The posts 102 guide the leading bag 38 therebetween and provide a contact surface for the bag 38 if the bag 38 is pulled at an angle other than parallel to the dispensing direction. In this manner, the posts 102 facilitate pivoting of the frame 12 with respect to the dispenser support 14 as shown in FIGS. 12-14 of the application.

As noted above, in the depicted embodiments of the bag dispenser 10, 100, the frame 12 includes a containment arrangement defining rails/guards 34 for preventing the bag roll 26 from sliding off the roller 24 once the bag roll 26 is slidably placed on the roller 24. In the example embodiment, the support arm 28 is a pivot arm that allows the roller 24 to be pivoted upwardly in order for the bag roll 26 to clear the rails 34 during loading of the bag roll 26.

Also as noted above, arrangements other than guards/rails 34 and a pivot arm 28 may be used to prevent the bag roll 26 from sliding off the roller 24 once the bag roll 26 is placed on the roller 24. For example, referring to FIG. 16, a roller 124 defining a throughhole 125 adjacent an end thereof and a clevis pin 127 may be used to keep the bag roll 26 on the frame 12 of the bag dispenser. The clevis pin 127 provides a contact surface perpendicular to the longitudinal axis of the bag roll 26 and keeps the bag roll 26 on the roller 124. It should be noted that a clevis pin 127 is simply one example arrangement and other removable structures that provide such a perpendicular contact surface may be used.

Referring to FIG. 17, a roller 224 defining an upward extension 227 at an end thereof may be used to prevent the bag roll 26 from sliding off the roller 224 once the roll 26 is placed on the roller 224. It should be noted that with the arrangement shown in FIG. 17, the bag roll 26 would have to be tipped or pivoted up to align the core 30 with the extension 227 and then tipped or pivoted down once clearing the extension 227 in placing the bag roll 26 on the roller 224.

Referring now to FIG. 18, a roller 324 having an integral pivoting end piece 327 is shown for preventing the bag roll 26 from sliding off the roller 324 once the roll 26 is placed on the roller 324. The roller 324 may have a groove provided therein with the end piece 327 attached to the end of the roller 324 with a pin 325. When the bag roll 26 is to be placed on the roller 324, the end piece 327 is pivoted to fit within the groove and aligned longitudinally with the roller 324 to allow the bag roll 26 to slide on. After the bag roll 26 is placed on the roller 324, the end piece 327 can be pivoted to a position where it provides a contact surface perpendicular to the longitudinal axis of the roller 324. In certain embodiments, the end piece can 327 be weighted in an offset manner or provided with a biasing mechanism to pivot automatically to a vertical position after the placement of the bag roll 26.

Now referring to FIGS. 19-21, as noted above, the second braking arrangement 40 of the bag dispenser 10 is of the type that may be used with a variety of different bag rolls having a variety of different core diameters. According to the embodiment depicted in FIGS. 1-9, the roller 24 includes a surface 52 that provides friction to the internal surface 54 of the core 30 of the bag roll 26. As noted previously, the friction surface 52 of the roller 24 might be provided in different ways, for example, using surface texturing, using a material of relative high static and kinetic coefficient of friction, using an adhesive material to provide a tacky surface, etc. With the application of enough friction, once the leading bag 38 is torn off, the rest of the bag roll 26 does not freewheel within the frame 12.

As also noted above, arrangements other than a roller 24 having a friction surface 52 may be used to reduce the rotational speed of the core 30 and to prevent freewheeling of the bag roll 26 after dispensing of the leading bag 38. For example, according to an example embodiment shown in FIG. 19, a roller 424 defining a plurality of circumferentially positioned springs 452 can be used. The springs 452 would apply a frictional force in a direction radially outwardly from the longitudinal axis of the roller 424 to slow down the core 30. It should be noted that any number of springs 452 may be used, as long as the springs 452 provide a frictional force on the inner surface 54 of the core 30. With this arrangement, the roller 424 may still be a type of roller that can accommodate a variety of different bag rolls having a variety of different core diameters.

FIG. 20 illustrates an arrangement wherein the roller 524 would include a pair of rods 525 that would define the main axle for allowing the core 30 of the bag roll 26 to rotate. The rods 525 may be interconnected at their ends through a U-shaped end piece (not shown). A weight piece 552 that is slidable in the up/down direction mounted on the rods 525 would provide the frictional force needed to slow down the bag roll 26. The weight piece 552 would be able to slide downwardly until contacting the bottom interior surface 54 of the core 30. Since the weight piece 552 is free to slide up and down with respect to the rods 525, with this kind of an arrangement, regardless of the relative size difference between the axle formed by the rods 525 and the core inner diameter, the weight piece 552 would take up the slack between the two diameters and provide the necessary friction on the bottom of the core interior surface 54. And, thus, the roller 524 would still be a type of roller that can accommodate a variety of different bag rolls having a variety of different core diameters.

FIG. 21 illustrates another arrangement for reducing the rotational speed of the core 30 of the bag roll 26 and preventing freewheeling of the bag roll 26 after dispensing no matter the size of the core 30. In the arrangement illustrated in FIG. 21, a biasing member 652 located at some portion on the frame 12 (between the support arm 628 and the edge of the bag roll 26 in the depicted embodiment) would slow down the rotation of the bag roll 26 by applying friction along a direction parallel to the longitudinal axis of the core 30. It should be noted that the depicted example is simply one example arrangement of reducing rotational speed of the core 30 by the application of an external biasing element 652 such as a spring and that other arrangements provided on other locations on the bag dispenser may also be used.

FIGS. 22-26 illustrate another embodiment of bag dispenser 700 having features that are examples of inventive aspects in accordance with the present disclosure. The bag dispenser 700 of FIGS. 22-26 includes features that are similar to the previously described and illustrated embodiments 10, 100 except for a number of differences that will be described herein.

Referring now specifically to FIGS. 22-24, in the bag dispenser 700, the support arm 728 that attaches the roller 724 to the frame 712 is a vertical structure, as opposed to a horizontal structure as in the previous embodiments 10, 100. Also, unlike in the previous embodiments, the support arm 728 of the bag dispenser 700 is fixedly attached to the frame 712 rather than being pivotally arranged as in the previous embodiments 10, 100. The support arm 728 is sized in length such that even a full bag roll 26 can rotate on the roller 724 without any portion of the frame 712 contacting the bottom surface 32 of the bag roll 26. In the embodiment of the bag dispenser 700 shown in FIGS. 22-26, the support arm 728 also acts a containment structure 734 for preventing the bag roll 26 from sliding off the opposite end of the roller 724 once the bag roll 26 has been slidably placed over a loading end 725 of the roller 724.

Further, unlike the previous embodiments of the dispensers 10, 100 discussed above, the bag dispenser 700 defines a first braking arrangement 736 that includes a braking plate 742 that is pivotally mounted to the support arm 728 of the bag dispenser 700 via a pivot arm 701. Unlike the previous embodiments of the bag dispensers 10, 100 wherein the first braking arrangement is defined by a braking plate that is removable for accommodating different types or thicknesses of bags, the floatability of the braking plate 742 of the bag dispenser 700 is provided by the pivoting arrangement. The pivotable braking plate 742 is configured to pivot along a plane parallel to the dispensing direction D. When mounting a bag roll 26 on the dispenser 700, by pivoting the plate 742, a leading bag 38 can be placed underneath the braking plate 742, in between the plate 742 and the frame 712.

Similar to the previous bag dispensers 10, 100, the braking plate 742 cooperates with a braking surface 748 to provide at least one point of contact therebetween for application of friction. The braking plate 742, even though heavy enough to apply a frictional force to the bag 38, is also able to adjust for variations in the bag thickness, texture by being floatable via the pivotable mounting arrangement.

As shown in FIGS. 22-26, the braking plate 742 defines a transition portion 743 that provides a curved contact surface 745 for guiding the leading bag 38 from the bag roll 26 to the area where friction is applied, between the plate 742 and the braking surface 748 of the frame 712. The curved contact surface 745 of the transition portion 743 may also provide additional friction to the leading bag 38 as the leading bag 38 is being pulled, while allowing the leading bag 38 to be able to smoothly slide and be unrolled from the bag roll 26.

Even though the bag dispenser 700 of FIGS. 22-26 has been depicted with a number of features that were noted for the previously described bag dispensers 10, 100 such as a removable tongue structure with a pincher/perforator, it should be noted that the dispenser 700 of FIGS. 22-26 may include any of the other features that have been described for the above dispensers of FIGS. 1-21, such as an accessory mount and/or different types of universal second braking arrangements.

For example, referring now to FIGS. 25-26, even though the bag dispenser 700 has been depicted with a roller 724 that is similar in structure to the roller 224 shown in FIG. 17, the bag dispenser 700 may include any of the above-discussed structures for mounting the bag roll 26 to the dispenser 700 and/or for braking arrangements for preventing freewheeling of the bag roll 26 after dispensing of the leading bags 38.

Similar to the roller 224 shown in FIG. 17, the roller 724 of the bag dispenser 700 defines an upward extension 727 at a loading end 725 thereof for preventing the bag roll 26 from sliding off the roller 724 once the bag roll 26 is placed on the roller 724. As discussed with respect to the roller 224 of FIG. 17, with the roller 724 used on the bag dispenser 700 of FIGS. 22-26, the bag roll 26 may have to be tipped or pivoted up in placing the bag roll 26 over the loading end 725 and then tipped or pivoted down once clearing the extension 727 in placing the bag roll 26 on the roller 724.

Although in the foregoing description, terms such as “top”, “bottom”, “front”, “back”, “right”, “left”, “upper”, and “lower were used for ease of description and illustration, no restriction is intended by such use of the terms. The dispensers described herein can be used in other orientations, depending upon the desired application.

The above specification, examples and data provide a description of the configuration and use of the devices therein. However, many embodiments of the disclosure can be made without departing from the spirit and scope of the inventive aspects.
